Final answer:
Struthio camelus, known as the ostrich, is a large flightless bird adapted for running and is unrelated to the emu despite appearing similar. They each share more genetic homology with flying birds in their respective regions than with each other.
Step-by-step explanation:
Struthio camelus is a large, flightless bird commonly known as the ostrich. It is known for being swift-footed and is the largest bird in the world. Flightless birds like the ostrich have lost their ability to fly throughout evolution and have developed traits suitable for their environments. The ostrich, along with others such as the kiwi, rhea, cassowary, and the extinct moa, has long legs and is adapted for running. Conversely, flightless birds like penguins are adapted for swimming.
Examining the shared genetic homology between emus and ostriches and their flying regional counterparts supports the idea that flightless birds adapt to their local environments and do not necessarily share a most recent common ancestor. This is the best explanation for the phenomenon stated in the student's question regarding the genetic analysis findings of emus and ostriches.
